Question

the second floor of a tiny house has a length of 11 feet. the bedroom is x feet wide is 3 feet wide. when two expressions always name the same value, they are called equivalent expressions. evaluate the expression 11(x + 3) if the width of the bedroom is 4 feet. 11(x + 3) = 11(□ + 3) substitute 4 for the variable, x. x ft 3 ft 11 ft 11 f a = 11(x + 3)

Explanation:

Step1: Identify the value of \( x \)

The width of the bedroom is given as 4 feet, so \( x = 4 \).

Step2: Substitute \( x = 4 \) into the expression

We substitute \( x = 4 \) into \( 11(x + 3) \), so we get \( 11(4 + 3) \). First, fill in the box with 4 as we substitute \( x = 4 \). Then, calculate inside the parentheses: \( 4 + 3 = 7 \). Then multiply by 11: \( 11\times7 = 77 \). But for the box, we just need to put the value of \( x \), which is 4.

Answer:

4
